Upgrading Cisco ONS 15327 Release 1.0.x or 3.3.x
to 3.4
Introduction
This document explains how to upgrade the Cisco ONS 15327 software from Release 1.0.x or 3.3.x to
Release 3.4. In Release 1.0.x, the CTC and network element software of the ONS 15327 retained
separate version numbers. Release 1.0.x of the ONS 15327 software contains network element software
1.0.x and CTC software 2.3.x. Release 1.0.2 of the ONS 15327 contains network element software 1.0.2
and CTC software 2.3.2. Beginning in Release 3.3.0, both the ONS 15327 network element software and
the CTC software are versioned the same.
Before beginning, write down the following information about your site; the data will be useful during
and after the upgrade: Date, Node Name, Node Location, Street Address, Site Phone Number, Node IP
Address, Subnet Mask, Dial Up Number, and Node ID.
Caution
Read each procedure before you begin the upgrade.
Caution
You cannot upgrade from ONS 15327 Release 1.0.0 directly to Release 3.4. If you are currently running
Release 1.0.0, you must first upgrade to Release 1.0.2 before upgrading to Release 3.4. Refer to
Upgrading Cisco ONS 15327 Release 1.0.x to 1.0.2 for instructions on performing an upgrade form
Release 1.0.0.
If you are currently running either Release 1.0.1, 1.0.2, or 3.3.x you may proceed with this upgrade.
Note
Procedures in this document are to be performed in consecutive order unless otherwise noted. In general,
you are not done with a procedure until you have completed it for each node you are upgrading, and you
are not done with the upgrade until you have completed each procedure that applies to your network. If
you are new to upgrading the ONS 15327, you may wish to check off each procedure on your printed
copy of this document as you complete it.

Upgrade Requirements
Upgrade Requirements
This section contains critical information that you must read before the upgrade process.
Read the Release Notes for Cisco ONS 15327 Release 3.4 before you begin this upgrade procedure.
CTC Workstation Requirements
Before upgrading the workstation to run CTC Release 3.4, verify all PC or UNIX workstation hardware
and software requirements.
•
A Windows or Unix workstation:
– IBM-compatible PC with a 486 or higher processor, CD ROM drive, and 128 MB RAM running
Windows 95, Windows 98, Windows 2000, Windows NT, or Windows XP
– UNIX workstation running Solaris
•
Browser software (select one):
– Netscape Navigator 4.73 or higher (Netscape Navigator is included on the ONS 15327 software
CD shipped with the node.)
– Netscape Communicator 4.61 or higher
– Internet Explorer 4.0 Service Pack 2 or higher
•
Note
The Java Policy and Java Runtime Environment (JRE), Release 1.3.1.02 (JRE 1.3.1.02 is included
on the ONS 15327 software CD)
After you upgrade to JRE 1.3.1.02, you will no longer be able to log into an ONS 15454 running Release
2.2.1 or prior, or an ONS 15327 running release 1.0.0. If you must later revert to a release that requires
a previous version of the JRE, you will have to reinstall Java and delete the jar files from your
workstation’s user “temp” directory after reverting all of the nodes in the network. If you are currently
running a release that is also compatible with JRE 1.3.1.02, or if you retain your JRE 1.2.2 installation,
the extra steps are not necessary.
IP Address Caveat
Disable all other Ethernet devices (such as a dial-up adapter) on the workstation that runs CTC.
If you have multiple IP addresses on your workstation, you should remove them; you cannot install
Release 3.4 if multiple IP addresses are running.
Telnet Session
Make sure all active telnet sessions to any node in the network are closed.
Back Up the Database
Before upgrading from Release 1.0.x or 3.3 to Release 3.4 software, you must back up the current
database for all nodes in the network.

Back Up the Database
Step 1
Log into CTC.
Step 2
From the node view, click the Maintenance > Database tabs.
Step 3
Click Backup.
Step 4
Save the database on the workstation's hard drive or on network storage. Use an appropriate file name
with the file extension .db (for example, myDatabase.db).
Step 5
Click Save. The Backup Complete dialog box appears.
Step 6
Click OK.
Step 7
Repeat Steps 1-6 for each node in the network.
Cisco recommends that you manually log critical information by either writing it down or printing
screens where applicable. This step is optional after you have backed up the database. Use the following
table to determine the information you should log; complete the table (or your own version) for every
node in the network.
Item
Record data here (if applicable)
IP address of the node
Node name
Timing settings
DCC connections; list all optical
ports that have DCCs activated
User IDs (List all, including at
least one super user)
Inventory; do a print screen from
the inventory window
Network information; record all
the information from the
Provisioning tab in the network
view.
Current configuration: linear,
etc.
List all protection groups in the
system; do a print screen from
the protection group window
List alarms; do a print screen
from the alarm window

Upgrade the Software
Upgrade the Software
After backing up the database and logging all of the required information, insert the Release 3.4 software
CD into the workstation (or otherwise acquire access to the software) and begin the upgrade process.
You must download and activate the software.
Caution
A traffic interruption of less than 60 ms on each circuit is possible during the activation, with Ethernet
traffic impacted for approximately one second during each XTC switch and also when each Ethernet line
card reboots (45–60 seconds per card).
Caution
Do not perform maintenance or provisioning activities during the activation phase.
There are two flash RAMs on the XTC card. An upgrade downloads the software to the backup RAM on
both the backup and active XTCs. This procedure does not affect traffic because the active software
continues to run at the primary RAM location; therefore, you can download the software at any time.
Download
Step 1
Check all nodes in the ring for existing alarms. Resolve any outstanding alarms before proceeding.
Note
During the software download process, an alarm, SFTWDWN, indicates that the software download is
taking place. This is normal and clears when the download is complete.
Step 2
Using CTC Release 2.3, or Release 3.3, log into the node from which you will download the software.
Note
Starting with the node most directly connected to your workstation will achieve the best download
performance; however, in some networks it may be safer to begin your upgrade at the farthest node and
proceed toward the one you are most directly connected to. This ensures that no node will be at risk of
being stranded if unforeseen circumstances cause the upgrade to fail. This issue is a matter of network
administration policy.
Step 3
From the CTC network view, click the Maintenance > Software tabs.
Step 4
Click Download. The Software Download dialog box opens.
Step 5
Click Browse to locate the software files. The File Open dialog box opens.
Step 6
Open the ONS 15327 folder.
Step 7
Select the file with the “.pkg” extension and click Open. The Software Download dialog box opens.
Step 8
In the list of compatible nodes, select the checkboxes for all nodes you are downloading the software
to.
Step 9
Enter the number of nodes you have selected in the “Concurrent Downloads” field.
Step 10
Click OK.

Upgrade the Software
Note
CTC will display the download status on the Maintenance > Software pane so you can monitor the file
transfer. The status changes to “complete” when the software has finished downloading. The software
download process can take 30 minutes or more, depending on the number of nodes in the network.
Activate the New Load
Log into and activate each node in the network, beginning with the node you performed the download
from.
Note
Cisco recommends that the first node you activate be a LAN-connected node. This ensures that the new
CTC jar files will download to your workstation as quickly as possible.
Note
Make sure all cards that are part of a protection group (1+1, 1:1, or 1:N) are active on the working card
of that protection group and that no protection switches are occurring. In other words, make sure that the
protect cards are in standby before proceeding.
Step 1
Perform a BLSR lockout appropriate for the software release from which you are upgrading. For
lockout procedures, refer to the user documentation for the specific software release.
Step 2
Log into the first node.
Step 3
Record the IP address of that node.
Step 4
Verify that the node has no active alarms. If alarms exist, clear them before proceeding.
Step 5
From the CTC node view, click the Maintenance > Software tabs.
Step 6
Verify that the protect version is 3.4.
Step 7
Click Activate. The Activate dialog box appears with a warning message. Click Yes.
Step 8
The “Activation Successful” message appears upon successful completion of the activation. Click OK
to begin the node rebooting process.
Step 9
After activating the node, wait until the software upgrade finishes at that node before continuing.
Each card installed in the node will activate and reboot, beginning with the standby XTC. Once the
standby XTC is fully activated and fully rebooted, the other XTC activates. Then the line cards reboot
consecutively from bottom to top (slot one to four). This process is service affecting for Ethernet traffic
only. Cisco recommends that you activate the new load during a maintenance window. Ethernet traffic
will be impacted for approximately one second during each XTC switch and again while each Ethernet
line card reboots. The Ethernet outage for any one of these cards could range from 45–60 seconds. After
all cards have rebooted, the standby XTC reboots again to ensure that all circuits are updated correctly.
The entire process takes up to 12 minutes. Once the standby XTC finishes its final reboot and all alarms
clear you can safely proceed to the next step.
Note
The system can take up to 12 minutes to reboot.

Upgrade the Software
Note
Step 10
During the rebooting process your CTC session will lose connection to the node and change to
network view. This is normal.
In CTC, choose File > Exit.
Note
Steps 10 and 11 are only necessary after upgrading the first node. For the remaining nodes, you
will still be disconnected and removed to the network view during the node reboot, but after the
reboot is complete, CTC will restore connectivity to the node.
Step 11
Follow all steps in the “Delete Cached Jar Files” procedure on page 6. When you have performed all of
the steps in that procedure, continue here with the next step (Step 11).
Step 12
Reconnect to CTC using the IP address from Step 2 (if the IP address is still in the browser location bar
you can simply hold down the shift key and click the browser Reload/Refresh button). The new CTC
applet for Release 3.4 will upload. Because this applet is backwardly compatible with the older version
of CTC, you still have network visibility while you are upgrading.
Note
Step 13
Only activate one node at a time.
Log into and activate each of the remaining nodes one at a time. After successful activation, wait ten
minutes before activating the next node.
Delete Cached Jar Files
When you upgrade or revert to a different CTC software load, you must reload CTC to your browser. In
most cases, you can do this by simply clicking “Delete CTC Cache” in your browser window; however,
in some circumstances, you may need to delete cache files from your browser’s directory, or from the
“temp” directory on your MS Windows workstation. If you have trouble reconnecting to CTC after
upgrading or reverting, follow the steps below.
Step 1
Delete cache files from your browser directory.
In Netscape:
a.
Choose Edit > Preferences > Advanced > Cache.
b.
Click Clear Memory Cache.
c.
Click OK.
d.
Click Clear Disk Cache.
e.
Click OK twice.
In Microsoft Internet Explorer:
a.
Choose Tools > Internet Options > General.
b.
Choose Delete Files.
c.
Select the Delete all offline content checkbox.
d.
Click OK twice.

Revert to Previous Load
Step 2
Close your browser.
Step 3
Delete cached files from your workstation (Windows systems only).
Step 4
a.
In your Windows start menu, choose Settings > Control Panel > System > Advanced.
b.
Click Environment Variables. This will show you a list of user variables and a list of system
variables.
c.
In the list of user variables, look for the variable “TEMP.” The value associated with this variable is
the path to your temporary directory where jar files are stored.
d.
Open the “TEMP” directory located in the path you just looked up.
e.
Select View > Details.
f.
Select and delete all files with “jar” in either the name or type field.
Reopen your browser. You should now be able to connect to CTC.
After deleting cached jar files, you should return to the referring procedure, either the “Activate the New
Load” procedure on page 5, or the “Revert to Protect Load” procedure on page 7, and continue with the
steps there.
Date Setting
If you are not using SNTP, the upgrade procedure can cause the Date setting to change.
Step 1
In CTC node view, click the Provisioning > General tabs.
Step 2
Set the correct date and click Apply.
Step 3
Repeat Steps 1 and 2 for each remaining node.
Revert to Previous Load
Before upgrading from Release 1.0.x, or 3.3.x to Release 3.4 software, you should have backed up the
current database at all nodes in the network (this is part of the “Upgrade the Software” section on
page 4). Cisco highly recommends that you record or export all critical information to your hard drive.
If you need to revert to the previous software load, you might need the database backup to restore your
original settings. To revert to the previous software load, use the following procedure.
Revert to Protect Load
Step 1
Record the IP address of the node.
Step 2
From the node view, click the Maintenance > Software tabs.
Step 3
Verify that the protect software displays 1.0.x or 3.3.x (the older release you were upgrading from).
Step 4
Click Revert. Revert activates the protect software. A dialog box asks you to confirm the choice.
Step 5
Click OK. This begins the revert and drops the connection to the node.

Manually Restore the Database
Step 6
Wait until the revert finishes at one node before continuing or reverting other nodes.
Note
Be patient. The system reboot might take up to 12 minutes to complete.
Step 7
Wait ten minutes before reverting another node.
Step 8
After reverting all of the nodes in the network, you must exit CTC and clear the Java cache. From the
File menu, choose Exit.
Step 9
In your browser window, click Delete CTC Cache.
Note
Step 10
It might also be necessary to delete cache files from your browser’s directory, or from the “temp”
directory on your MS Windows workstation. If you have trouble reconnecting to CTC, refer to
the “Delete Cached Jar Files” procedure on page 6.
Log back into the last node that was reverted with the IP address that you recorded in Step 1. This
uploads the appropriate CTC applet for Release 1.0.x to your workstation.
Manually Restore the Database
Provisioning might be lost during a revert. When this happens it is necessary to restore the database
backup.
Caution
This process is traffic affecting and should be performed during a service window.
Step 1
From the CTC node view, click the Maintenance > Database tabs.
Step 2
Click Restore. The “Open…” dialog box opens.
Step 3
Select the previously-saved file and choose Open.
The database will be restored and the XTCs will reboot.
Step 4
Once the XTCs have rebooted, log back into CTC and verify that the database is restored.
Wait one minute before restoring the next node.
